So many factors...apples, oranges, and grapefruit. Various affecters, including
software level, may be involved. In particular, keep the following in mind
(from my notes):
Selective Backup, more overhead than Running a Selective Backup can be
Archive expected to entail more overhead than a
comparable Archive operation, in that
more complex retention policies are
involved in Backup policies than in
Archive. Remember that Archive retention
is based purely upon time, whereas
Backup involves both time and versions
decisions. File expiration candidates
processing based upon versions (number
of same file) is performed during client
Backups (in contrast to time-based
retention rules, which are processed
during a later, separate Expiration).
The more versions you keep, the more
work the server is distracted with at
Backup time.
